Hi. 8)

My cylinder head is stamped 68-72. I have been through all my bits and trawled the BSAOC archive but cant find that No. So what have I got.

Must admit that I would like to get this as right as possible, so that I can buy the correct valves etc. Are the valves A65 interchangeable. Must confess that previously I would have just bought A65 Valves because I wasn't aware they differed.

So despite the haggard looks I am still young enough to learn????????????

Mike :) :)

Hiya Mr Editor, :)

In truth, no, not as a matter of course. I have a selection of books that have arrived unbidden in my drawer. However now that you have been so kind as to prompt me, in future I shall do so. Seriously thank you.

Julian Hi.
Thanks for your input, now I understand more fully. Further question,-- As I have no idea what year my cylinder head is from, are the lower valve collars interchangeable. And are there any others that might fit. I know that I can buy new ones but I wish to avoid that wherever possibly for such simple parts.

Thanks for that. Now I know where I'm going. Some of these books are simply unbelievable wit duff info.

Go a step further--are the different valve collars interchangeable??Not that I know what year my cylinder head is.

Good morning. I am rebuilding an A65 engine to Thunderbolt spec. I have a camshaft No 68-0473 which I am lead to believe is high lift???. Out of a Spitfire or something of that ilk.(According to Draganfly,-----I don't know) If I remember rightly the correct one is 67-356??

I know the dear old Thunderbolt with standard pistons etc doesn't need that amount of breath, so what will be the probable effect if I use it
I suspect very little but I would be interested in your thoughts.

Heres a quickie. If I have a daylight only MOT does it mean that I cant ride it on rainy or overcast or any other days with some limiting visibility, when the law requires "dipped headlights"

I have purchased an A65 Cylinder Head minus the inlet manifold and my thoughts are that the A50 and A65 are probably different

I am confused about this because although the A50 carb bores are different I cant find a definitive answer about the manifolds.
In one book they appear to be the same, another book says they are different and a further book doesn't even mention them.

So any light on this one would really be appreciated. I would also like to hear from any one who has one or has a cream crackered head they might part with

Mike :o :o :o

HI I found the method that suits me is as mentioned just a piece of cord and a strong pull. I also offer up a prayer in which most words appear to begin with "F"

There is a Post Office Vehicle Owners Club. They may be able to assist or at least tell you whether it was ever PO.

That's bril.

It almost seems that it is entirely dependant upon whose desk it lands on. Dunno but I hope my luck runs that way.



I think we've identified a serious issue that is going to take some revolutionary thinking to get it sorted. A few individuals are not going to achieve anything. Even an individual Owners Club would not carry sufficient power or clout to get anything sorted.

My thoughts are that it will take a very serious joined up approach by ALL the many clubs to achieve anything down this line. AND it will need some big hitters.

Some thought as to what is trying to be achieved and what might be achievable. Then a powerful leader.

My thoughts are running ahead at the moment. but I am seriously blocks by the uptight and  intransigent stance adopted the system.

I think its not only a lack of training but a lack of knowledge and a total lack of interest. Obviously not taught at university. Further the argument that if you tick all the boxes correctly. then you will be OK; no longer holds good

We'll see

The situation with regard to DVLA appears to be getting worse. Its now at the point where you need the level of evidence required for conviction in a murder trial.

So if after very careful consideration you (or anyone else) considers themselves hard done by do this: -

Write to the CAO DVLA Swansea. Write to the minister of transport and write to your local MP.

It may not work but but but  if we load them up enough maybe someone will listen. Trouble is they have the big guns. The longer we just sit back the longer it will go on and the worse it will get.

Its almost as if there is an orchestrated movement to stop restorations without going down the "SVA full test route"



Hi. Too late for you but the best thing in these circumstances is to get the seller to obtain a new V5 prior to selling. He is entitled to it but afraid that you are not.

It can still fail.
